A laser pointer was the weapon of choice for one Phils fan at Saturday’s game.

A fan at the Cards/Phillies game used a strategically placed laser
pointer to try and distract the St. Louis hitters. In the top of the
seventh inning the fan first used it on Julio Lugo, who eventually
struck out. Then the fan tried to distract Albert Pujols before umpire
Jim Wolf called time and tried to find the fan. Security went to the
section but the culprit was never caught, according to ESPN.

I think the dumbest thing about this is that someone felt that outside assistance was needed to render Julio Lugo ineffective.
